PIGKLING APPARATUS.

Application filed March 5, 1928. Serial No. 259,043.

This invention relates broadly to metal pickling apparatus, and it has for its primary object to provide an improved mechanism whereby the usual pickling racks are reciprocated in the fluid bath contained by the pickling tanks.

A further object is to provide an apparatus of the character mentioned embodying means whereby vertical reciprocation of the pickling racks is effected without the employment of guides.

A still further object is to provide, in an improved pickling apparatus, rack carriers, or spider-like supports, having such relatively small dimensions and light weight that transportation thereof to and from their operative positions relative to the pickling tanks is attended with greatly reduced inconvenience and with relatively small danger of injury to the workmen.

With these and other objects in view, the invention resides in the features of construction, combinations of elements and arrangement of parts which will hereinafter be fully described, reference being had to the accompanying drawings, in which- Figure 1 is a top plan view of the invention F igure 2 is a sectional elevation in which ihe section is taken substantially on line 2--2,

h igiire 3 is a sectional elevation on line 3-3, Fig. 1; and

Figure l is a perspective view of the racksupport or carrier.

Referring to said drawings, 1 and 2 designate companion pickling tanks of rectangular form disposed in spaced parallel relation and containing the pickling fluid, or bath. Located outwardly from and adjacent to the opposite ends of each of the tanks are suitable supports, as concrete pedestals or piers 3, upon which are rigidly mounted heavy upright castings, or brackets, 4, each of wh1ch constitutes a support for alined complemental bearings 5 and 6. J ournaled in each set of said bearings 5 and 6 are the opposite ends of a short rock shaft 7. Each of the rock shafts 7 located at opposite ends of tank 1 has fixed thereon between the bearings 5 and 6 the middle portion of a walking beam 8, and similar walking beams 9 are fixed on the rock shafts located at the opposite ends of tank 2.

Pivotally attached to the opposite ends of each of the walking beams 8 and 9 are the upper ends of links 10 and 11 by means of which two rectangular frames 12 and 13 are suspended in overhanging relation to the tanks 1 and 2, respectively, said frames being deslgned as supports for carriers 14 from which are suspended the usual pickling racks 15.

Each of the frames 12 and 13, as herein shown, comprises parallel longitudinally extending side members, each formed of two rigidly attached channel irons 16, and transverse I-beams 17 connecting saidside members. Each of said side members carries a trunnion 18 in fixed relation to' each of its ends, said trunnions, as herein shown, being formed on the outer end of a block-like insert 19 which is received between and riveted to the adjacent ends of the companion channel irons 16.

For the purpose of providing for alternate vertical reciprocations of the supporting frames 12 and 13, in which reciprocations said frames are at all times maintained in horizontal, or non-tilted, positions, the outer ends of each pair of walking beams 8 and 9 are disposed in suspending relation to the adjacent, or outer, side of the underlying frame, and the inner ends of each pair of said beams occupy like relation to the adjacent, or inner, side of the other, or non-underlying frame. Otherwise expressed, the walking beams 8 have their links 10 disposed in supporting relation to the trunnions 18 which are carried by the outer side member of the frame 12, while the links 11 of said beams 8 support the trunnions carried by the inner'side member of the frame 13. Likewise thelinks 10 and 11 of walking beams 9 carry the trunnions of the outer side member of the frame 13 and the inner side member of the frame 12, respectively.

Fixed upon the outer end of each of the rock shafts 7 is a depending crank arm 20, and pivotally attached to and connecting the two crank arms at each of the opposite ends of the machine is an oscillatory member 21, herein shown as of triangular form, but which,

obviously, may be of ordinary bell-crank form with the outer ends of its arms pivotally connected to said crank arms, and which, therefore, is hereinafter termed a bell crank. Pivotally connected to the lower, or an ular, portion of the bell crank is an end of a orizontal pitman 22 adapted to be reciprocated by any appropriate type of power transmission means and whereby said crank arms 20 are actuated to swing back and forth for effecting rocking of the walking beams 8 and 9.

Each of the frames 12 and 13 constitutes a support adapted for the reception in overlying seated relation thereto of a portable carrier or spreader 14 of rectangular form and which is preferably fabricated of structural steel, as is best shown in Fig. 4. Said carrier has suitably arranged depending hooks 23 with which are engageable the upper ends of suspension rods 24upon which is carried the sheet-supporting racks or crates 15. A lifting bail 25 borne by each carrier is designed for receiving in carrying relation thereto the hoisting hook of a crane or other form of mechanical transfer device whereby the raks'are transported to and from the pickling tanks. Suitable guide members 26 arranged in pairs are provided in suitable relation on the side members of the frames 12 and 13 whereby the side members of the carriers 14, as the latter are being lowered, are guided to proper seating positions on said frames.

It will be noted that the carriers 14 have such relatively short length that, in efiecting "transfer to and from their positions over the tanks, the danger of injury to the workmen is much reduced below that which exists in transporting the prevailing long pole-like forms of rack carriers.

As is manifest, operation of the apparatus hereinbefore described eifects vertical reciprocation of the rack-carried sheets without the employment of guides or other parts which require frequent repairs or renewals with attendant high cost of upkeep. Further, the structure described provides means whereby pickling of the sheets may be effected with a minimum of agitation-of the fluid which constitutes the pickling bath, which is a particularly desirable feature in the production of certain kinds of high-grade sheets.

In pickling apparatus, the combination with companion tanks, of walking beams mounted adjacent to the opposite ends of each tank a supportin frame-supported over each tank by said walking beams each frame having its outer side supported by the outer ends of the adjacent beams and its inner side supported by the inner ends of the non-adjacent bearns whereby each frame is at all times maintained in horizontal position portable rack-suspension means adapted to seat upon each of said frames and means for rocking said walking beams to effect alternate vertical reciprocation of said frames for elevating and lowerin the rack suspension means.
